Thank you for the compliment on my system... yes.. it is a PIA putting my system together especially when you have limited space and you are trying to put a crap load of stuff in it. But you have to be patient when you are putting it together and in the end it is all worth it.
The part I am dreading is that when the new parts come in, tomorrow, I will have to remove the cooling system to retrofit the new pump/res (i'll end up having to fabricate some new mounting brackets) and remove the mb so as I make way for the new cooling block due to the different mounting stuff... (crap)....
so you are asking about the red coating that is wrapping the cooling block, as it is shown in this picture?
it is liquid rubber. You can get the stuff from Home Depot and Lowe's home improvement big box store. They come in red and black. It is the stuff that if you have a tool or whatever.... and you want to coat it for insulation or whatever the purpose.... this is the stuff to do it.
The reason I used it to coat the cooling block is to insulate it from the possibility of developing condensation on the metal surface. I had noticed that if I crank on the controller to full power... that the metal surface will develop condensation. At this time I just coated the cooling block and will monitor the TEC tanks. If at anytime the TEC tank develop condensation, I will coat them too... but at the moment, it is not necessary. But with the new block... I dont think i'll have to do this since the top is of clear acrylic which in itself an insulator versus a metal surface which will develop condensation much faster.
As the word pump failure..... well, for me.... I consider my pump not quite failed ..... it just NOISY... it still pumps... I cant see how a little bit of air would cause this noise... in my case it was 1.75" worth of air bubble. When you look at the lines real close while it is operation... there are no bubbles moving through the system. It is a solid wall of water. The only thing I could see is the bubble would congregate or trap at the upper half of the pump causing air pockets and the impellar to ocillate.... plus the pump is very simple in design... the motor/magnet is stationary.. then you have a impellar with a magnet that when power is applied the impellar spins... I am kinda thinking that these impellar are not well balanced and that they vibrate very easily causing the impellar's magnet to rub against the motor housing causing the noise. To me a total failure is when the pump is not pumping or in otherwords the impellar is not spinning.... I starting to believe that the pump is just low in quality when it comes to longevity.
I will post up pictures of before and after and will give you guys the result of my quest for total quietness operation...
